UNIVERSAL JOINT AND SHOCK-ABSOREING SPRTNGS FOR HEADLIGHTS;

eraeio.

To all whom it may concern Be it known that I, PERCY S. BAILEY, a citizen of the United States, residin at Lynn, in the county of Essex, State of 1 as sachusetts, have invented certain new and useful Improvements in Universal Joints and Shock-Absorbing Springs for Headlights, of which the following is a specification.

My invention relates toimprovements in shock absorbing supports. More specifically, it relates to supports for headlights the cars when couplings are made.

which are subjected to considerable jarring,

pended claims. In the accompanying drawmg illustrating one form of my invention in connection with a headlight,'the figure is a side elevation partly in section.

-after.

numeral 10 indicates a headlight having a housing or frame 11, in which is suitably mounted a reflector 12 and. a source of light. 13, which I have shown as an incandescent lamp. The housing 11 is closed at its open I end by a door 1 1 suitably hinged at 15, and 40 having a window'16. Thelower part of the housing 11 forms a supportmg platform 17, which is provided with a suitable number of openings 18, preferably four, in rec tangular relation, but two of these openings are indicated in the drawing. The openings 18 each are provided with an internal flange 19 or other suitable shoulder, preferablylocated midway in said Op8Il1I1gS 1I1 order: to form spring seats on both surfaces of the platform 17,. as will appear herem- A base 20 spaced-fromthe platform 17 is rovided with a suitable number of openings 21 coinciding with the opemngs 19.

Application filed November 24:, 1920. Serial No. 426,163.

The openings 21 are each provided with an internal flange 22, which forms a flat shoulder on its upper surface to serve as a spring seat and is hemispherical onits lower surface to form a socket as shown in the figure. The platform 17 and base 20 are united by bolts 23 which pass through the openings 21 and 19. These bolts are of smaller diameter than the openings. through which.

they extend in order to permit .a relative lateral movement between the base 20 and the headlight 10. The bolts 23 are provided atone end with hemispherical shaped heads 24 arranged to fit into the sockets formed by the respective flanges 22. At their opposite 'ends, the bolts 23 are threaded to receive nuts 25 which are secured by lock nuts 26. The base 20 and member 17 are separated by suitable compression springs 27 which surround the bolts 23. These springs are seated on the respective flanges 22 and bear against the lower surface of the respectivefianges 19 at their upper ends, as shown. 1

Suitable compression springs 28, which surround the respective bolts23, are interposed between the nuts 25 and the platform 17 and are seated on the respective flanges 19.

It will therefore be seen that the headlight 10 is cushioned between the springs 27 and 28. While I have shown these springsas spiral 1n form, they could be helical or any 7 other suitable form. Referring to the drawing in which the When an unusual shock is sustained, the bolts 23 will ive in whatever direction the %1eadlight carries them, due to the ball and socket arrangement of the belts in the base 20 and due to the openings 19 and 21 being larger than the bolts. movement of the bolts isretarded however by the springs 27 and 28, thus breaking the shock in a manner readily understood, which springs return the headlight to its normal positionafter theforce of the shock Whilel have described my invention as embodied in concrete form in accordance with the provisions of the patent statutes, it should be understood that I do not limit my invention thereto, since various modifications thereof will suggest themselves to those skilled in the art without departing The I by Letters Patent of the United States,

I a base, a supporting member, spherically 1. A shock absorbing support comprising headed bolts loosely connecting said base and said supporting member to permit of a relative lateral movement, springs on said bolts located on both sides of said supporting member arranged to cushion said member therebetween, and sockets on said base arranged to receive said spherically headed bolts, and thereby permitsaid bolts to move universally. v

2. A shock absorbing support comprising a base provided with openings, a supporting member having openings, bolts having spherical heads loosely extending through said openings thereby uniting the base and supporting member, spring seats on the upper and lower surfaces of the supporting member concentric with the openings there of, spring seats on the upper surface of the base concentric with the openings thereof,

ing a supporting platform, of a shock absorbing support comprising a base, spherically headed bolts connecting said base and supporting wall arranged to permit relative lateral movement between these parts, springs on said bolts located on both sides of the supporting platform arranged toi cushion said platform therebetween, and

sockets in said'base arranged to receive said spherically headed bolts andthereby permit said bolts to move universally. In witness whereof, I have hereunto set 'my hand this 18th day ofNovember, 1920.
